THREAD HOLDER Filed Aug. 29, 1947 INVENTOR. IMF/[V L. JAMMOIYS %%M6Wfld/wdam v ATTORNEYS Patented Dec. 20, 1949 UNITED STATES PATENT OFFICE1 Claim.

The present invention relates to thread holders and has for its objectthe provision of a device which will support a ball or cone of threadsuch as is ordinarily used for crocheting and the like, so that the ballor cone cannot roll away as the strand is being unwrapped therefrom bythe user.

The principal object is to provide a holder of this class having aspindle and platform rotatably mounted on a ball bearing, which willcarry the ball of thread and permit the strand to be unwrapped therefromwith a minimum of effort.

Another object is to design a holder for this purpose, that cannot beeasily tipped or upset by the pull exerted in unwrapping the thread.

These and other objects will appear from the following description andthe illustration in the accompanying drawing, in which:

Figure 1 is a perspective view of my holder with a ball of threadpositioned thereon.

Figure 2 is a vertical sectional view, and

Figure 3 is a bottom plan view of the device.

The base I of my holder will be preferably circular in plan View and maybe made of any suitable material to give it proper weight and will be ofsuch diameter as to prevent tipping of the holder when in ordinary use.A central opening 2 in the base will house an annular ball bearing 3,the top member of which will be free to rotate in said opening while thebottom memher is held stationary therein. The bottom of the opening 2will be of slightly greater diameter than the main opening and willprovide an annular recess for a disc plate 4 secured by screws to thebase and serving to hold the bearing in place. The opening 2 is reducedin diameter at the upper side of the base, as at 5, and an opening 6 ofequal diameter is formed centrally through the plate 4.

A cylindrical thread spindle 1 designed to receive a ball of thread,such as 8, is reduced at its lower portion, as shown at 9, to form ashoulder I0. A circular platform member H has a central aperture l2through which the reduced portion of the spindle is inserted, the upperface of the platform member bearin against the shoulder l0. Snuglyfitting the portion 9 below the platform and supporting said platform onthe spindle,

is a sleeve l3 which rests upon the upper member of the bearing 3. Thelower extremity of the portion 9 is threaded to receive a nut l4, and asleeve it; extends through the opening 6 and is positioned between theunder side of the bearing and the said nut.

From the foregoing it will be clear that the weight of the spindle 1 andplatform If is carried by the bearing 3 through the sleeve l3 and thatthe upper half of said bearing is free to rotate with the spindle andplatform. Ease of operation is thus provided and the user may unwrap thethread from the ball with a minimum of effort.

Having now described the invention, what is claimed is:

A thread holder, comprising a base, an annular ball bearing assemblymounted in said base, said assembly being formed with a cylindricalopening therethrough axially thereof, said base being formed with anoversize cylindrical opening therethrough in alignment with said openingin said bearing, a thread spindl including a reduced lower end providinga shoulder, an axiallyapertured thread platform freely rotatable on saidreduced lower end of said spindle and providing a seat for saidshoulder, said reduced lower end of said spindle being freely rotatablein said opening in said bearing assembly, and a sleeve freely rotatableabout said reduced lower end of said spindle between said bearingassembly and said platform whereby to support the latter and saidspindle on said bearing assembly.
